old storytime

This year I started walking to my aunt's house after school since my mum is busy with work and can't pick me up, a few months ago I was walking to her house and I saw this older guy (probably in his twenties) with a red shirt walk by a few times but I just thought he must be lost or something, so I kept walking and listening to music with my earbuds. Right when I was almost at the door, he walks up to me and tries to take my phone from my pocket. I freezed for a second and slapped his hand, then said something like "what the fuck do you think you're doing, idiot?" and he just walked away like nothing happened. I walked into the house and told my aunt about it, she called the police a bunch of times but they never came (wow, crazy! unbelievable!) so now I always keep a pocket knife, just in case (like I'd ever use it lol)
